Why is the weight of an object on the moon 1/6th its weight on the earth?
Let ME be the mass of the Earth and m be an object on the surface of the Earth. Let RE be the radius of the Earth. According to the universal law of gravitation, weight WE of the object on the surface of the Earth is given by,
Let MM and RM be the mass and radius of the moon. Then, according to the universal law of gravitation, weight WM of the object on the surface of the moon is given by:-
`"Where, "M_E=5.98xx10^24kg," "M_M=7.36xx10^22kg`
Therefore, weight of an object on the moon is `1/6` of its weight on the Earth.
State whether the following statement is true or false :
Tire weight of an object on the earth is about one-sixth of its weight on the moon.
A body has a weight of 10 kg on the surface of earth. What will be its weight when taken to the centre of the earth ?
